Title: Implantation device for introduction of hormone pellets - into connective tissue of cattle
IPC: A61D7/00
Filed: 1973-08-28
Abstract: Implantation device is intended for the introduction of pellets, based on natural hormones, under the skin of animals. The object is to increase the growth of the animal and facilitate the anabolism of proteins and so produce developed carcasses, rich in meat. The implanter consists of a moulded plastic handle with external projections for improving the grip. The internal boring is extended by a chamber for receiving the cartridge (I), contg. the pellets, in the operation position. This chamber is located opposite the inlet of a hypodermic needle and immediately below a magazine contg. a pile of identical cartridges. (I) is in the lowest, active position in the discharging chamber. The cartridges consist of cylindrical sleeves; each contains a number of pellets corresponding to a unit dose to be discharged and implanted in a single thrust of the push-rod. The emptied cartridge is ejected on the return stroke of the rod. The device is suitable for a number of successive operations which can all be effected rapidly on grazing cattle. As the dose is divided into a number of pellets, a large surface area is obtd. for the diffusion and absorption of the active prods. in the midst of the conjunctive tissues of the receiving animal.

Title: Centrifugal drier with steam injector feed system - for massecuite in sugar refineries
Inventor: MERCIER ANDRE
IPC: C13B30/06
Filed: 1974-06-17
Abstract: Centrifugal drier, for the sepn. of suspended solids from a viscous liq. comprises a funnel-shaped basket with a conical wall, it is driven around a vertical axis and its internal face is lined with a sieve. The prod. to be sepd. is fed to the lower part of the basket by a device consisting of two concentric pots, fixed to the hub of the basket. The end of the feed pipe dips into pot which has a crenellated edge. The prod. to be sep. enters through the feed pipe, the lower part of the basket and moves upwards along the sieve under the action of the centrifugal force. The liq. phase passes through the sieve and flows along the wall of the latter to the evacuation orifices in the upper part, it is finally collected in a tank. The solid particles slide on the sieve to the upper edge of the basket where they are ejected into another tank. The device is for use with massecuite produced in sugar refineries. The steam does not mix appreciably with the prod. but divides it into fine threads or droplets.

Title: Ultrasonic generator for material testing - incorporates velocity measuring and pulse coincidence circuits
IPC: G01N29/07
Filed: 1974-10-23
Abstract: A CRT display of ultrasonic pulses from a sample undergoing non-destructive tests, also incorporates a digital propagation velocity meter. These are devised to enable pulse time delay to be measured precisely. The ultrasonic generator has a master pulse clock which also triggers a sweep delay, a brightness delay, and a null control circuit arranged in sequence. The clock also starts a timing pulse which is stopped at the end of the total delay caused by these three circuits. A coincidence detector compares the trailing edge of this pulse with the centre of the received echo pulse. At the same time an identification bright-up spot appears coincident with the echo on the CRT screen.

Title: Electric motor driven horse racing game - has competitors advancing on endless belt with obstacles and variable handicap
IPC: A63F3/00
Filed: 1975-03-07

Title: Long duration electronic delay circuit - uses unijunction transistor triggered at anode via diode
IPC: H03K17/13
Filed: 1975-10-16
Abstract: The electronic delay circuit, providing an output some minutes after triggering, is intended to overcome problems associated with the very high resistance or capacity values normally required for delays of this order. The circuit is based on the use of a programmable unijunction transistor (36) triggered at the anode via a diode (38) fed from a bridge circuit. This includes the basic CR charging route part of which serves to limit the discharge current when the capacitor is shorted out by a manual switch (35). The supply to the CR is via a diode (30) providing a half wave changing voltage, triggering from this same source occurring when the circuit constants allow the capacitor voltage to rise to some given value.

Title: Electrical network loop impedance measurement - involves resistance and inductance circuits interconnected by switch
IPC: G01R27/16
Filed: 1977-03-29
Abstract: The method of measurement uses the fall in voltage method initiated by the connection of a known load Z into the network. The method includes a preliminary adaptation operation which consists of modifying the nature of the known load Z until the fall in voltage is a maximum. Modification of the load Z is achieved by modifying its argument phi whilst retaining its modulus ant. The variable known load Z (1) consists of a resistance network (2) which can be switched by a first stage (3) of a switch (4) in series with an inductance network (5). The inductance network (5) can be switched by a second stage (6) of the switch (4). Each resistance, inductance network switched simultaneously in series by the switch (4) has an impedance whose modulus nstant and whose argument phi is variable and depends upon the position of the switch.
